Part winding start motor wiring diagram. Motor wiring diagram 466703 12 lead single voltage wye start delta run or part winding start revised. You can connect them for a delta start or a wye start. Connect motor lead 1 to l1 typically black motor lead 2 to l2 typically red and motor lead 3 to l3 typically blue. It is to be used only for voltage recovery and must not be left on the start connection for more than 2 to 3 seconds. 182014 nidec motor corporation st. Such motors might be dual winding motors in which case you can wire them for a part winding start.
The winding in the motor must be split in order for it to use a part winding start. How it works and advantages. Microsoft word 466703 author. Typical wiring diagrams always use wiring diagram supplied on motor nameplate connection diagrams co leads part winding weg three phase motors volts 12 lead part winding 12 10 11 12 3 l1 l2 12 10 11 64 5 78 9. A portion of the winding either half or two thirds will be connected when the motor is started. 452018 part winding start.
Motors that divide the winding in half will se e a 50 reduction in current at start up. 182014 11406 pm. Motors that split the winding two thirds to one third energizing two thirds. Dual voltage motors have split windings but they can only be started on the lower voltage winding. This method used only a portion usually one half but sometimes two thirds of the motor winding increasing the impedance seen by the power system. Two pa rallel circuits the motor will only be exposed to a portion of the current at start up d epending on the design.
If its a three phase six lead motor how do you get the wye start.
